Don't use a strip-type thermometer, which you hold on your baby's forehead, to check your baby's temperature. Strip thermometers only show the temperature of your baby's skin, not her body. It's also best not to use an old-fashioned, mercury-in-glass thermometer.
If your prawns are smaller, spread a piece of aluminum foil or banana leaf on the grill first, then place prawns on top. Or skewer the shrimp with satay sticks (if wood, soak in water first). Baste the prawns the first time you turn them with a little of the leftover sauce. Grill 3 to 5 minutes each side. Prawns are done when the flesh turns from translucent to pinkish-white (and the shells turn a very attractive bright pink).
Once your water has come to a full rolling boil, add your shrimp and stir to separate them. Cover with lid and turn off your stove burner and let sit. Small shrimp ( more than 50 per pound) will be cooked in 2 to 3 minutes, Large(31-35 per pound) shrimp in about 6 to 8 minutes. Note: These times are for 1 pound of shrimp. To check for doneness, take a shrimp out and cut through the thickest part, it should be opaque.
